here's a quick start to get you going. Without seeing some markup to build a relationship between the button and the #info container would need to splice() to pull number off the button ID and splice the #info to create function to open correct one. Some markup would help as there are a number of easier ways to do this depending on container configuration

Add a class .infoButton to your buttons unless you already have a class just for them. You can do this with ID's but as with CSS it's easier to use classes in many instances with jQuery. Following only works if *only* one of them will be checked

$(".infoButton").each(function () {

    if ($(this).is(':checked')) {
        $(".infotext").hide();
        //// Open appropriate #info .....seeing markup here will help, or use splice to filter ID's. Adding a class to the #info's will probably help also
       
});

Hi there,

i'am new to jquery so my question is maybe too easy for you? ;)

I got the following: 3 Radiobuttons which each i added a click event
that shows up a new div with some information about the value of this
radio button. This works fine.
Now when i load the page and passing a PHP variable to the script one
radio button is checked by default. This also works but the div with
the information doesn't appear.

Is there a way to check which button is selected on $(document).ready
and then fireing the event which is attached to this button?

Here is a code snipped of my first jquery script:

$(document).ready(function(){

 $(".infotext").hide(); // onload hide the infofield

 // for each button hide the infofield and fade in just the one i need
- this works :)
 $("#btn_1").click(function(){
                    $(".infotext").hide();
                    $("#info1").fadeIn("slow");
 });
 $("#btn_2").click(function(){
                    $(".infotext").hide();
                    $("#info2").fadeIn("slow");
 });
 $("#btn_3").click(function(){
                    $(".infotext").hide();
                    $("#info3").fadeIn("slow");
 });
});
